Cerebral aneurysms are localized dilations of arteries in the brain. They can be saccular, fusiform, or dissecting in shape. The most common location is on arteries in the Circle of Willis. Risk factors include hypertension and smoking. Symptoms may include sudden headache, nausea, vision changes, or seizures. Diagnosis is made using CT, MRI, or CT angiography. Treatment options are surgical clipping or endovascular coiling to prevent rupture and bleeding in the brain. Nursing management focuses on monitoring for complications and educating on risk factor modification.

1. CEREBRAL
ANEURYSM

2. • An aneurysm is a localized or diffuse dilation
of an artery with a diameter at least 50%
greater than the normal size of the artery

3. TYPES
• TRUE ANEURYSM
• FALSE ANEURYSM
According to morphology
• Fusiform
• Saccular
• Dissecting

4. Saccular
• rounded berrylike
outpouchings that arise
from arterial bifurcation
points, most commonly
in the circle of Willis.
• dilatations of a vascular
lumen caused by
weakness of all vessel
wall layers

5. • AN ELONGATED SPINDLE-SHAPED DILATION OF AN
ARTERY
• roughly cylindrical and affects the entire circumference of
the

6. DISSECTING
ANEURYSM
• Pseudoaneurysm
• should be used for encapsulated, cavitated,
paravascular hematomas that communicate with the
arterial lumen
MAY ARISE SPONTANEOUSLY
TRAUMA

7. LOCATION
• A common location of cerebral aneurysms is on
the arteries at the base of the brain, known as
the Circle of Willis.
• Approximately 85% of cerebral aneurysms
develop in the anterior part of the Circle of Willis,

9. • Weakness in blood vessel wall
• Atherosclerosis
• Hypertension
• Severe trauma
• Weakness in blood vessel wall.
• smoking
• Alcohol

10. • NO EARLY SIGNS (some)
• Sudden headache
• Nausea and Vomiting
• Vision impairment
• Loss of Consciousness
• Nuchal rigidity
• Seizures
• Dysphagia
• Pupillary changes

11. DIAGNOSIS
• CT SCAN
• MRI SCANNING
• CT ANGIOGRAPHY

16. MANAGEMENT
• SURGICAL MANAGEMENT
The goal is to eliminate blood flow into the aneurysm
ENDOVASCULAR ANEURYSM REPAIR
CRANIOTOMY + REPAIR

17. • Medical Therapy
smoking cessation and blood pressure control

18. • Surgical Clipping
a V-shaped, silver clip to the neck of an internal
carotid artery aneurysm.
A small metal clip (usually made from titanium) is then
applied to the neck (base) of the aneurysm

19. • Endovascular Coiling
Guglielmi detachable coils, known as GDCs,
are soft wire spirals originally made out of platinum
These coils are deployed (released) into an aneurysm via
a microcatheter that is inserted through the femoral artery
of the leg and carefully advanced into the brain.

20. • The microcatheter is selectively advanced into the
aneurysm itself, and the microcoils are released in a
sequential manner
• Once the coils are released into the aneurysm, the blood
flow pattern within the aneurysm is altered, and the slow
or sluggish remaining blood flow leads to a thrombosis
(clot) of the aneurysm.
• thrombosed aneurysm resists the entry of liquid blood,
providing a seal in a manner similar to a clip.
Endovascular coiling is an attract
